摘要： A helmet includes a shell configured to extend over ears of a user with integrated acoustic ear cups having a polygonal cushion/seal formed by an upper hexagonal portion connected to a lower inverted triangular portion with a wedge-shaped profile/thickness thinner in the upper portion than at least some of the lower portion to provide non-uniform side loading that improves wearer comfort and reduces acoustic leak paths for passive or active noise reduction (ANR). A headband, headset, or earmuffs for hearing protection include a polygonal cushion/seal with a wedge-shaped profile/thickness to facilitate acoustic sealing and user comfort.

摘要： The present disclosure discloses an acoustic input and output apparatus. The acoustic input and output apparatus may include a loudspeaker assembly, a sound-pickup assembly configured to pick up a sound signal, and a connection assembly including an elastic member, wherein a first end of the elastic member may connect to the loudspeaker assembly, and a second end of the elastic member may connect to the sound-pickup assembly. The elastic member may be configured to cause an average amplitude attenuation rate of vibrations within a phonic frequency band generated by the loudspeaker assembly to be larger than or equal to 35% in a process that the vibration transmits from the first end of the elastic member to the second end of the elastic member.

摘要： Disclosed are a method for controlling the volume of a wireless headset, a wireless headset and a mobile terminal. The method comprises: when the mobile terminal is connected to a wireless headset in an in-ear state, acquiring a target play volume range of the wireless headset; adjusting the play volume of the wireless headset within the target play volume range; when volume determination information from the wireless headset is received, determining that the play volume of the wireless headset at the moment the volume determination information is received is a target play volume value; and adjusting the play volume of the wireless headset to be the target play volume value. The play volume of a wireless headset suitable for a user can be automatically and quickly set.

摘要： An acoustic apparatus includes a sound-emitting unit that acoustically outputs a sound signal, at least one sensor that periodically detects accelerations of the user in three directions including a front-rear direction, a left-right direction, and an upper-lower direction, a vibration sound peak detection unit detecting a peak of a vibration sound based on a movement of the user when detection values of the accelerations in the front-rear direction, the left-right direction, and the upper-lower direction satisfy a predetermined condition, and a signal processing unit that determines whether a time difference at which the peak of the vibration sound is detected is periodic. When it is determined that the time difference is periodic, the signal processing unit sets a gain of a cancellation signal to be suppressed from the sound signal acoustically output from the sound-emitting unit based on the peak of the vibration sound.

摘要： A hearing protection device is presented. The hearing protection device includes a first hearing protection unit and a second hearing protection unit. Each of the first and second hearing protection units include a microphone that receives ambient sound, a processor that provides level dependent attenuation of the ambient sound, and a speaker that broadcasts the sound into a user's ear. The hearing protection device also includes a first communication unit, which broadcasts a digital push-to-talk signal over a first communication protocol. The first communication protocol is a low energy communication protocol. The hearing protection device also includes a second communication unit, which broadcasts a digital communication signal over a second communication protocol. The hearing protection device also includes a processor that facilitates pairing of the hearing protection device with a mobile device that receives the push-to-talk signal and, based on the push-to-talk signal, receives the digital communication signal and transmits the digital communication signal over a cellular network.

摘要： A microphone system, comprises a first transducer, for generating a first acoustic signal, and a second transducer, for generating a second acoustic signal. A high-pass filter receives the first signal and generates a first filtered signal, and a low-pass filter receives the second signal and generates a second filtered signal. An adder forms an output signal of the microphone system as a sum of the first filtered signal and the second filtered signal.
